s1, compounding, namely bonding a raw paper layer and an aluminum foil layer together through an adhesive layer, wherein the bright surface of the aluminum foil layer faces outwards;
s2, coloring: coloring the compounded bright surface of the aluminum foil layer to obtain a first semi-finished product, wherein the effective component of the mixed coating liquid ingredient for coloring is water-based resin emulsion;
s3, coating: coating gloss oil on the first semi-finished product subjected to the compounding and coloring procedures by using a coating machine, and arranging a high-gloss water-based gloss oil coating layer on the surface of the first semi-finished product to obtain a second semi-finished product;
s4, embossing: the second semi-finished product penetrates through the space between the first pressing roller and the second pressing roller at a preset speed, and concave-convex pictures and texts formed by the shading and/or patterns on the first pressing roller and/or the second pressing roller are transferred on the second semi-finished product by adjusting the gap between the first pressing roller and the second pressing roller to obtain a third semi-finished product, wherein the second pressing roller is arranged below the first pressing roller;
s5, slitting, namely segmenting the third semi-finished product into strips, rolling or cutting the strips into flat paper with a certain specification, and performing quality inspection and finished product packaging and warehousing.
2. The method of claim 1, wherein the step S1 is embodied as: and uniformly coating the adhesive layer between the raw paper layer and the aluminum foil layer in an oven at the speed of 100m/min, wherein the temperature of the oven is 110 ℃.
3. The method for manufacturing the high-gloss embossed lining paper as claimed in claim 1, wherein the aqueous resin emulsion comprises the following components in percentage by mass:

leveling agent: 0.1 percent;
dispersing agent: 0.05 percent;
defoaming agent: 0.05 percent.
4. The method for manufacturing high gloss embossed liner paper according to claim 1, further comprising a drying process between steps S2 and S3: and returning the first semi-finished product to the oven for drying to form the cured color forming film.
5. The method for manufacturing the high gloss embossed liner paper according to claim 1, wherein the ground pattern and/or the pattern on the first press roller and/or the second press roller are formed on the surface of the cylindrical plate of the first press roller and/or the second press roller by using a computer laser engraving technology.
6. The method for manufacturing the high-gloss embossed lining paper as claimed in claim 5, wherein the first pressing roller is an embossing mother roller, the second pressing roller is a nylon pressing roller, the second semi-finished product passes through the first pressing roller and the second pressing roller at a speed of 80m/min, and concave-convex patterns formed by the ground patterns and/or patterns on the embossing mother roller are transferred to the second semi-finished product by adjusting the gap between the first pressing roller and the second pressing roller, so as to obtain a third semi-finished product.
7. The method for manufacturing the high-gloss embossed liner paper as claimed in claim 6, wherein the nylon press roller is arranged right below the embossing mother roller.
8. The method for manufacturing the high-gloss embossed lining paper as claimed in claim 5, wherein the ground texture is a net-shaped or strip-shaped or micro-hole-shaped micro-engraved ground texture arranged on a plane part of the first pressing roller and/or the second pressing roller.
9. The high gloss embossed liner paper, which is prepared by the method for manufacturing the high gloss embossed liner paper according to any one of claims 1 to 8, comprises a raw paper layer, an adhesive layer and an aluminum foil layer which are arranged in sequence from bottom to top, wherein the bright surface of the aluminum foil layer faces outwards, and the bright surface of the aluminum foil layer is further coated with a high gloss aqueous gloss oil coating layer, and the high gloss aqueous gloss oil coating layer is transferred with concave-convex patterns.
10. The high gloss embossed liner paper according to claim 9, wherein the relief pattern is engraved on the high gloss aqueous varnish coating layer by computer laser engraving.
